Abstract:
PROBLEM TO BE SOLVED: To optimally control power and other parameters, in a two-way communication system, by utilizing a GPS receiver. SOLUTION: A selective-call transceiver (20) in a messaging system having a plurality of transmitters (90, 94, 99), is constituted of a receiver module (26), a transmitter module (22) coupled to the receiver module and a controller coupled to the receiver module and the transmitter module for controlling the operation of the selective call transceiver. Additionally, the selective-call transceiver also comprises a GPS receiver (24), coupled to the controller for receiving GPS information, wherein the controller uses the GPS information to assist in the control of functions selected from among a group, consisting of transmitter power control, site selection switching, sub-zone selection switching, forward error correction, retry transmission decisions, Doppler-frequency shift, synchronization, and frequency scanning and selection.
